Next week I have to look at an S4C robot.  
Has this type already an ethernet card onboar? I thought the S4C+ always has. But this type is older, is the ethernet card standard, optional, or not available?  
Suppose there is something wrong with the operating system, do I need a boot disk? What if the bootdisk is lost?  
Or is a key enough to generate a new robotware with robinstal?
